digital switching allowing transfer of fluid from one microfluidic channel to another selectivity separate and transfer analytes by size and mass mix reactants efficiently and separate fluids with disparate characteristics in addition there is a natural analogy between the fluid handling capabilities of nanofluidic structures and the ability of electronic components to control the flow of

early in the twentieth century there was interest in highmass air wells but despite much experimentation including the construction of massive structures this approach proved to be a failurefrom the late twentieth century onwards there has been much investigation of lowmass radiative collectors these have proved to be much more successful the highmass air well design attempts to cool a large mass of masonry with cool nighttime air entering the structure due to breezes or natural convection in the day the warmth of the sun results in increased atmospheric humidity when moist daytime air enters the air well it condenses on the presumably cool masonry none of the highmass collectors performed well knapens aerial well being a particularly conspicuous example the problem with the highmass collectors was that they could not get rid of sufficient heat during the night – despite design features intended to ensure that this would happen while some thinkers have believed that zibold might have been correct after all an article in journal of arid environments discusses why highmass condenser designs of this type cannot yield useful amounts of water we would like to stress the following point to obtain condensation the condenser temperature of the stones must be lower than the dew point temperature when there is no fog the dew point temperature is always lower than the air temperature meteorological data shows that the dew point temperature an indicator of the water content of the air does not change appreciably when the weather is stable thus wind which ultimately

the first person to reasonably predict the power needed for sustained flight otto lilienthal the first person to become highly successful with glider flights was also the first to propose thin curved airfoils that would produce high lift and low drag building on these developments as well as research carried out in their own wind tunnel the wright brothers flew the first powered airplane on december 17 1903 during the time of the first flights frederick w lanchester martin kutta and nikolai zhukovsky independently created theories that connected circulation of a fluid flow to lift kutta and zhukovsky went on to develop a twodimensional wing theory expanding upon the work of lanchester ludwig prandtl is credited with developing the mathematics behind thinairfoil and liftingline theories as well as work with boundary layers as aircraft speed increased designers began to encounter challenges associated with air compressibility at speeds near the speed of sound the differences in airflow under such conditions lead to problems in aircraft control increased drag due to shock waves and the threat of structural failure due to aeroelastic flutter the ratio of the flow speed to the speed of sound was named the mach number after ernst mach who was one of the first to investigate the properties of the supersonic flow macquorn rankine and pierre henri hugoniot independently developed the theory for flow properties before and after a shock wave while jakob ackeret led the initial work of calculating the lift and drag of supersonic airfoils theodore von karman and hugh latimer dryden introduced the term transonic to describe flow speeds between the critical mach number and mach 1 where drag increases rapidly this rapid increase in drag led aerodynamicists and aviators to disagree on whether supersonic flight was achievable until the sound barrier was broken in 1947 using the bell x1 aircraft by the time the sound barrier was broken aerodynamicists understanding of the subsonic and low supersonic flow had matured the cold war prompted the design of an everevolving line of highperformance aircraft computational fluid dynamics began as an effort to solve for flow properties around complex objects and has rapidly grown to the point where entire aircraft can be designed using computer software with windtunnel tests followed by flight tests to

principles of physics the most relevant being the following three principles conservation of momentum which is a consequence of newtons laws of motion especially newtons second law which relates the net force on an element of air to its rate of momentum change conservation of mass including the assumption that the airfoils surface is impermeable for the air flowing around and conservation of energy which says that energy is neither created nor destroyedbecause an airfoil affects the flow in a wide area around it the conservation laws of mechanics are embodied in the form of partial differential equations combined with a set of boundary condition requirements which the flow has to satisfy at the airfoil surface and far away from the airfoilto predict lift requires solving the equations for a particular airfoil shape and flow condition which generally requires calculations that are so voluminous that they are practical only on a computer through the methods of computational fluid dynamics cfd determining the net aerodynamic force from a cfd solution requires adding up integrating the forces due to pressure and shear determined by the cfd over every surface element of the airfoil as described under pressure integration the navier – stokes equations ns provide the potentially most accurate theory of lift but in practice capturing the effects of turbulence in the boundary layer on the airfoil surface requires sacrificing some accuracy and requires use of the reynoldsaveraged navier – stokes equations rans simpler but less accurate theories have also been developed these equations represent conservation of mass newtons second law conservation of momentum conservation of energy the newtonian law for the action of viscosity the fourier heat conduction law an equation of state relating density temperature and pressure and formulas for the viscosity and thermal conductivity of the fluidin principle the ns equations combined with boundary conditions of no throughflow and no slip at the airfoil surface could be used to predict lift in any situation in ordinary atmospheric flight with high accuracy however airflows in practical situations always involve turbulence in the boundary layer next to the airfoil surface at least over the aft portion of the airfoil predicting lift by solving the ns equations in their raw form would require the calculations to resolve the details of the turbulence down to the smallest eddy this is not yet possible even on the most powerful computer so in principle the ns equations provide a complete and very accurate theory of lift but practical prediction of lift requires that the effects of turbulence be modeled in the rans equations rather than computed directly these are the ns equations with the

dormant endospore b subtilis can divide symmetrically to make two daughter cells binary fission or asymmetrically producing a single endospore that is resistant to environmental factors such as heat desiccation radiation and chemical insult which can persist in the environment for long periods of time the endospore is formed at times of nutritional stress allowing the organism to persist in the environment until conditions become favourable the process of endospore formation has profound morphological and physiological consequences radical postreplicative remodelling of two progeny cells accompanied eventually by cessation of metabolic activity in one daughter cell the spore and death by lysis of the other the ‘ mother cell ’ although sporulation in b subtilis is induced by starvation the sporulation developmental program is not initiated immediately when growth slows due to nutrient limitation a variety of alternative responses can occur including the activation of flagellar motility to seek new food sources by chemotaxis the production of antibiotics to destroy competing soil microbes the secretion of hydrolytic enzymes to scavenge extracellular proteins and polysaccharides or the induction of ‘ competence ’ for uptake of exogenous dna for consumption with the occasional sideeffect that new genetic information is stably integrated sporulation is the lastditch response to starvation and is suppressed until alternative responses prove inadequate even then certain conditions must be met such as chromosome integrity the state of chromosomal replication and the functioning of the krebs cycle sporulation requires a great deal of time and also a lot of energy and is essentially irreversible making it crucial for a cell to monitor its surroundings efficiently and ensure that sporulation is embarked upon at only the most appropriate times the wrong decision can be catastrophic a vegetative cell will die if the conditions are too harsh while bacteria forming spores in an environment which is conducive to vegetative growth will be out competed in short initiation of sporulation is a very tightly regulated network with numerous

uses image projection and stereoscopic sets as their primary area of digital investigation another example of digital theatre is computer theatre as defined by claudio s pinhanez in his work computer theatre in which he also gives the definition of hyperactor as an actor whose expressive capabilities are extended through the use of technologies computer theatre in my view is about providing means

culture by google arts and culture since the beginning of the 2020 pandemic the fashion industry has suffered strong economic losses as sales plummeted and jobs were lost but it has since learned to digitally recover through virtual clothing catwalks and showroomsamidst the covid19 pandemic fashion is among the industries that have been forced to adapt their commercial and creative strategies to better suit the social distancing measures therefore the digital channel has since seen a rise in use offering live shopping and has been highlighted as the only way to overcome physical barriers it is also believed that these changes will prevail in years to come as reported by wgsnfashion brands and wellknown personalities in the industry spread welfare messages on social media and brands such

ordered by inclusion moreover there does not exist a region included in all of the regions included in g intuitively an abstractive class defines a geometrical entity whose dimensionality is less than that of the inclusion space for example if the inclusion space is the euclidean plane then the corresponding abstractive classes are points and lines inclusionbased pointfree geometry henceforth pointfree geometry is essentially an axiomatization of simonss 1987 83 system w in turn w formalizes a theory in whitehead 1919 whose axioms are not made explicit pointfree geometry is w with this

of whitehead 1919 has a single primitive binary relation k defined as xky ↔ y x hence k is the converse of proper part simonss wp1 asserts that proper part is irreflexive and so corresponds to g1 g3

identification double dissociationverbal report is widely considered to be the most reliable indicator of consciousness but it raises a number of issues for one thing if verbal reports are treated as observations akin to observations in other branches of science then the possibility arises that they may contain errors — but it is difficult to make sense of the idea that subjects could be wrong about their own experiences and even more difficult to see how such an error could be detected daniel dennett has argued for an approach he calls heterophenomenology which means treating verbal reports as stories that may or may not be true but his ideas about how to do this have not been widely adopted another issue with verbal report as a criterion is that it restricts the field of study to humans who have language this approach cannot be used to study consciousness in other species prelinguistic children or people with types of brain damage that impair language as a third issue philosophers who dispute the validity of the turing test may feel that it is possible at least in principle for verbal report to be dissociated from consciousness entirely a philosophical zombie may give detailed verbal reports of awareness in the absence of any genuine awarenessalthough verbal report is in practice the gold standard for ascribing consciousness it is not the only possible criterion in medicine consciousness is assessed as a combination of verbal behavior arousal brain activity and purposeful movement the last three of these can be used as indicators of consciousness when verbal behavior is absent the scientific literature regarding the neural bases of arousal and purposeful movement is very extensive their reliability as indicators of consciousness is disputed however due to numerous studies showing that alert human subjects can be induced to behave purposefully in a variety of ways in spite of reporting a complete lack of awareness studies of the neuroscience of free will have also shown that the experiences that people report when they behave purposefully sometimes do not correspond to their actual behaviors or to the patterns of electrical activity recorded from their brainsanother approach applies specifically to the study of selfawareness that is the ability to distinguish oneself from others in the 1970s gordon gallup developed an operational test for selfawareness known as the mirror test the test examines whether animals are able to differentiate between seeing themselves in a mirror versus seeing other animals the classic example involves placing a spot of coloring on the skin or fur near the individuals forehead and seeing if they attempt to remove it or at least touch the spot thus indicating that they recognize that the individual they are seeing in the mirror is themselves'</li><li>'neti neti sanskrit नति नति is a sanskrit expression which means not this not that or neither this nor that neti is sandhi from na iti not so it is found in the upanishads and the avadhuta gita and constitutes an analytical meditation helping a person to understand the nature of the brahman by negating everything that is not brahman one of the key elements of jnana yoga practice is often a neti neti search the purpose of the exercise is to negate all objects of consciousness including thoughts and the mind and to realize the nondual awareness of reality neti neti meaning not this not this is the method of vedic analysis of negation it is a keynote of vedic inquiry with its aid the jnani negates identification with all things of this world which is not the atman in this way he negates the anatman notself through this gradual process he negates the mind and transcends all worldly experiences that are negated till nothing remains but the self he attains union with the absolute by denying the body name form intellect senses and all limiting adjuncts and discovers what remains the true i alone lcbeckett in his book neti neti explains that this expression is an expression of something inexpressible it expresses the ‘ suchness ’ the essence of that which it refers to when ‘ no other definition applies to it ’ neti neti negates all descriptions about the ultimate reality but not the reality itself intuitive interpretation of uncertainty principle can be expressed by neti neti that annihilates ego and the world as nonself anatman it annihilates our sense of self altogetheradi shankara was one of the foremost advaita philosophers who advocated the netineti approach in his commentary on gaudapada ’ s karika he explains that brahman is free from adjuncts and the function of neti neti is to remove the obstructions produced by ignorance his disciple sureshvara further explains that the negation neti neti does not have negation as its purpose it purports identity the sage of the brihadaranyaka upanishad ii iii 16 beginning with there are two forms of brahman the material and the immaterial the solid and the fluid the sat ‘ being ’ and tya ‘ that ’ of satya – which means true denies the existence of everything other than brahman and therefore there exists no separate entity like jiva which

meaning of meaning 1975 putnam stated that we can easily imagine pairs of individuals that are microphysical duplicates embedded in different surroundings who use the same words but mean different things when using them for example suppose that ike and tinas mothers are identical twins and that ike and tina are raised in isolation from one another in indistinguishable environments when ike says i want my mommy he expresses a want satisfied only if he is brought to his mommy if we brought tinas mommy ike might not notice the difference but he doesnt get what he wants it seems that what he wants and what he says when he says i want my mommy will be different from what tina wants and what she says she wants when she says i want my mommy externalists say that if we assume competent speakers know what they think and say what they think the difference in what these two speakers mean corresponds to a difference in the thoughts of the two speakers that is not necessarily reflected by a difference in the internal make up of the speakers or thinkers they urge us to move from externalism about meaning of the sort putnam defended to externalism about contentful states of mind the example pertains to singular terms but has been extended to cover kind terms as well such as natural kinds eg water and for kinds of artifacts eg espresso maker there is no general agreement amongst content externalists as to the scope of the thesis philosophers now tend to distinguish between wide content externalist mental content and narrow content antiexternalist mental content some then align themselves as endorsing one view of content exclusively or both for example jerry fodor 1980 argues for narrow content although he comes to reject that view in his 1995 while david chalmers 2002 argues for a two dimensional semantics according to which the contents of mental states can have both wide and narrow content critics of the view have questioned the original thought experiments saying that the lessons that putnam and later writers such as tyler burge 1979 1982 have urged us to draw can be resisted frank jackson and john searle for example have defended internalist accounts of thought content according to which the contents of our thoughts are fixed by descriptions that pick out the individuals and kinds that our thoughts intuitively pertain to the sorts of things that we take them to in the iketina example one might agree that ikes thoughts pertain to ikes mother and that tinas thoughts pertain to tinas but insist that this is because ike thinks'</li><li>'normal
